Added more global parameters to /admin/unused API endpoint (formally /admin/dud)
and also managed to remove /admin/unused from API documentation UI.
Added results slicing to /assets/all
Added /assets/orderbook API call that returns open asset orders
Added /assets/trades that returns successful asset trades
Added POST /assets/issue stub
Unified HSQLDB connectionUrl to public variable inside Controller class.
Can't deploy v1 ATs with isFinished=true flag as that prevents later
transactions sending messages (during import of v1 chain).
Some future hard-fork code will need to set all v1 ATs to "finished".
Changed DB's "TransactionRecipients" to "TransactionParticipants" to
properly support API call to find all transactions 'involving' a
specific address. Support code needed in Block and Transaction with
some transaction-specific overrides for Genesis and AT transactions.
Removed old, deprecated calls from Transaction/TransactionRepository
Moved HSQLDB database properties from connection URL to explicit
SQL statements in HSQLDBDatabaseUpdates. They didn't work in
connection URL during DB creation anyway.
Retrofitted HSQLDB Accounts table with public_key column instead of
rebuilding it later.
Fixed incorrect comments in IssueAssetTransactionTransformer regarding
v1 serialization for signing.
Re-imported v1 chain to test latest changes.
Some initial BTC cross-chain support. (Needs more work).
Unified timestamp for V2 switchover to block version 4,
applicable to several transaction types.
Qora-specific interface to CIYAM ATv2 library.
Beware: some areas still work-in-progress!
Now using ATv2 dated 20181101172102
ATData now uses byte[] creatorPublicKey instead of String creator.
TransactionData now has hashCode() and equals() methods,
which is needed for new Transaction Comparator,
used to sort transactions within a block,
AT-first, then timestamp, then signature.
AT-Transactions generate their own signatures using SHA2-256 of serialized data.
Arbitrary Transactions try to clean up their files when orphaned.
Deploy AT Transactions now check creation bytes (even for old v1 ATs).
Deprecated Transaction.getBlock() as it doesn't seem used
and would be better to simply have getHeight() rather than
a method that 'knows too much' about Blocks/BlockData.
Corresponding TransactionRepository.getBlockDataFromSignature()
also deprecated.
Loads more comments.
Tidied up some SQL: mainly correcting case,
moving PRIMARY KEY clauses to end of CREATE TABLE,
removing unnecessary columns from indexes.
Added "type" column to TransactionCreatorIndex so users can find
their transactions and optionally filter by type.
In BlockTransactions table, transaction_signature is now UNIQUE
as a transaction cannot be included in more than one block.
Various AT-related HSQLDB table and index changes.
ArbitraryTransactions transformer fixed to always return a list of payments,
even if empty. (Previously could return null which broke things).
Added simplistic block generator.
NOTE: unit tests broken due to pending upgrade to JUnit 5
ATData no longer needs deploySignature as a link back to DeployATTransaction,
but does need creator and creation [timestamp].
"creation" is critical for ordering ATs when creating/validating blocks.
Similar changes to ATStateData, adding creation, stateHash (for quicker
comparison with blocks received over the network), and fees incurred
by running AT on that block.
Also added more explicit constructors for different scenarios.
BlockData upgraded from simplistic "atBytes" to use ATStateData (above)
which has details on ATs run for that block, fees incurred, and a hash
of the AT's state. atCount added to keep track of how many ATs ran.
ATTransactions essentially reuse the GenesisAccount's publickey as
creator/sender as they're brought into existence by the Qora code
rather than an end user. ATTransactionData updated to reflect this
and the AT's address used as a "sender" field.
Account tidied up with respect to CIYAM ATs and setConfirmedBalance
ensures there is a corresponding record in Accounts (DB table).
Account, and subclasses, don't need "throws DataException" on
constructor any more.
Fixed bug in Asset Order matching where the matching engine
would give up after first potential match instead of trying others.
Lots more work on CIYAM AT, albeit mainly blind importing of old
v1 ATs from static JSON file as they're all dead and new
v2 implementation is not backwards compatible.
More work on Blocks, mostly AT stuff, but also fork-based corruption
prevention using fix from Qora v1.
Payment-related transactions (multipayment, etc.) always expect/use
non-null (albeit maybe empty) list of PaymentData when validating,
processing or orphaning.
Mainly a change in HSQLDBTransactionRepository.getPayments()
Payment.isValid(byte[], PaymentData, BigDecimal, boolean isZeroAmountValid)
didn't pass on isZeroAmountValid to called method - whoops!
Lots of work on ATTransactions themselves.
MessageTransactions incorrectly assumed the optional payment was always
in Qora. Now fixed to use the transaction's provided assetId.
Mass of fixes/additions to HSQLDBATRepository, especially fixing
incorrect reference to Assets DB table!
In HSQLDBDatabaseUpdates, bump QoraAmount type from DECIMAL(19,8)
to DECIMAL(27,8) to allow for huge asset quantities.
You WILL have to rebuild your database!
ATs can create AT-Transactions which contain payments (of any asset) and/or messages.
Legacy Qora1 DeployATTransactions create AT records in the repository but set to "finished"
so that they never execute.
More repository support for ATs.
In HSQLDB, create a new TYPE called ATStateHash which is used to verify the same AT outcome
on a per-block basis.
Added Accounts.account as a foreign key to AccountBalances with ON DELETE CASCADE.
ATStates now include state_hash and fees on a per-block basis.
ATTransactions now include asset_id.
When transforming DeployATTransactions, don't include any signature when collating bytes for signing!
NB: we're still using HSQLDB svn r5836
Updated README.md
Added log4j2.properties file for logging!

Fixed Block so correct block hash and timestamps are generated,
especially when previous/next block versions differ.
Added extra call in BlockTransformer to aid this.
Fixed GenesisTransaction.isValid's incorrect amount test.
Fixed comments in TransferAssetTransaction and incorrect use of BlockChain.getVotingReleaseTimestamp()
instead of BlockChain.getAssetsReleaseTimestamp().
Added new TYPEs to HSQLDBDatabaseUpdates, and set LOB granularity to 1KB for AT use.
Added AT_address column to DeployATTransactions in HSQLDB.
Added ATs, ATStates and ATTransactions tables.
(You will need to discard existing database and rebuild).
Fixed incorrect byte array output in IssueAssetTransactionTransformer,
where Asset "references" were not processed correctly.
Added support for BigDecimal serialization to a byte-array size other than the standard 8.
